Jon canines; on BALTIMORE, MARYLAN RA I L JOINT. j

Be it known that I, JoHNN Gunman, a citizen of the Republic of Germany,residing at Baltimore and State of vMaryland,have invented certain newand useful Improvementsin a Rail Joint, of which the following-is aspecification. I i

This invention relates to: railway rails, and ;has. more particular]reference to a joint construction between the meeting ends of'the railsections. 7

The primary object of my; invention is to provide a rail'joint whereinthe necessity of employing connecting fish plates, chairs and thelikewill be dispensed with and wherein vibrations of: the adjacent railswith respect to each other will also be substantially, overcome andpreventing the dis-alinement of the meeting of the rails in bothhorizontal and vertical directions which is adisadvantage in the presenttype rail joint. A further object is to provide a joint whereintheadjacent ends of the rail section may be rapidly and efficiently securedtogether without requiring bolts, or other similar connections.

zVVith the foregoing and other objects in view as the nature of theinvention will be better understood, the. same comprises the novel form,combination and arrangement of parts hereinafter more fully describedand shown in the accompanying drawing and claimed. In the drawing,wherein like reference characters indicate corresponding. partsthroughout the several views Figure l-is a fragmentary side elevation ofa pair of rail sections interconnecting through the medium of my presentjoint.

Fig. 2 is a bottom plan view thereof, Fig. 3 is a horizontal sectionthrough the joint, and

Fig. 4 is a perspective of the rail end interconnecting member.

Now having particular reference to the drawing, there are disposed apair of rail sections 55 that are adapted to be interconnected in end toend relation.

"In carrying out my invention, the opposite ends of these'rail sectionshave their web portions enlarged at opposite sides of the sections asindicated at 6'6, the enlargement being preferably of such thickness asto extend flush with the tread of the railsection as clearly shown inFig. 1.

ends with spaced key plates 1 Application filedDecember 1, 1925. SerialNo. 72,462.

.sExte-nding through the base of each rail section at its end and intothe thickened portion thereof are spaced vertical slots 7, 8 and f).that are preferably of various widths as shown in Fig. 2, that are incommunication with each other and separated by similarly spaced ribs101O and 11l1, said. ribs being'preferably of a width complementary tothe width of the slotsat the inner sides thereof.

The outer slots 9 of the-rail sections open at the edges of the railsection, and extending thereacross at the lower edge of the enlarged webportion 'are'slots 12, Fig. 1.

The joint further includes the provision of an interlockingbar or plateshown clearly in'Fig. 4: and designated generally 13. I Thisinterlocking bar isformed at its opposite 7 and 8"8 of substantiallysimilar dimensions as the slots 7 and 8 in the opposite ends of the railsections, the same being interconnected through the medium of webs10-10'.'

Intermediate the ends of the locking bar the same is'provided'with arelatively wide key plate 9 of substantially similar dimensions totheoutermost slot'9 of the rail sections when said rail sections have beenplaced in end to end relation as shown in Fig. 2. This intermediate keyplate is formed centrally with a cross slot 12 which is also ofsubstantially similar dimension with the cross slots 12 in the ends ofthe rail sections After the key memberhas been properly 1 insertedintermediate the ends of the rail sections, a key piir'lat is passedthroughthe slots 12 in the rail sections and slot 12" in the 1nember13.One end of this pin is headed as at 15, while the opposite end 105thereof is provided with fingers 1616that may be bent at right angles tothe key "against the adjacent web portions of the rails for preventingaccidental disengagement of the member 14 from the member 310 if andrail sections. This key let will effectively leek the member 13 withinthe adj acent ends of the rail sections and also prevent any verticalmovement of the sections with respect to each other.

It will thus be seen that I have provided a novel, simple and ettieientform of rail joint that is well adapted for all of the purposesintended, and even though I have herein shown and described the mostpraetieal embodiment of the invention with whieh I: am at this timefamiliar, it is never theless to be underetood that minor ehanges naryhe made" therein without. departing from the spirit and seope of theappended claim.

Having thus described an invention, what 1 elaim as new and LlGSUG tosecure by llietters Patei'it is:

In a joint for the meeting ends of rail sections wherein said railseetions are termed at their opposite ends with thickened web portionaHush with the tread of the weetiiins, said thickened portions beingprovided with spaced vertieal slots terminatin; at one end within thethickened portion and at their opposite ends through the raihhaaee,spacing ribs between the slots,

the outermost slots of the sections being provided with cross slots atthe base of the rail sections, an interlocking: bar provided at itsopposite ends with locking plates interconnected through the medium ofWebs, said plates adapted to engage upwardly within the innermost slotsof the rail seetion, said interlocking member being formed intermediateits ends with an additional locking plate for CilgflgPlliQlli within theouter slots of the rail aeetions and being provided: with a crossv sloteoinplemei itary to the cross alote ot' the outer web slots" ot saidrail seetions, and a locking membeii llllitlliittl to be dispoeedthrough the slots of the intermediate lot-king plate of said meme herand the cross slots of the rail seetiona, for maintaining the lockingmember in acsoeiation: with the slots in the rail set rtionsi saidi laetmentioned member being hewded at one end and provided at its-oppositeend with fingers that are adapted to be bent at right angles with: resiieet to the member alongside oi? the webs of the rails; for preventingaeeizdental disengagement of the member from said slot.
